how much and where should i add the timing generally speaking? ive got my tune pretty much dialed in i believe, but when it was tuned, it was on 93 octane. id like to make a seperate tune for the 110 torco they sell up the street. is there a general rule of thumb for how much timing to add and where to add it? this is for a supercharged setup by the way. 10 psi or so on a t trim, 9.1:1 355

 

Anyone?
